Sigmund Freud was born 150 years ago, in May 1856, and went on to revolutionise the way we think about ourselves. Along with Darwin, Marx and Einstein, he is considered one of the key thinkers of the modern world. However, he excites huge controversy, with virulent opponents and loyal champions still battling out the meaning of his work. Introducing Freud''s irreverent and witty approach, which has made it a bestseller throughout the world, demystifies Freud's psychoanalysis. It tells the incredible story of Freud's life and ideas from his upbringing in 19th-century Vienna to the gradual evolution of his theories on the unconscious, dreams and sexuality. Including for the first time a thought-provoking discussion of Freud with Jonathan Miller, this is the ideal introduction to the life and work of this challenging and seminal thinker.
